If you didn't press Volume Up quickly enough, it will boot into Android and overwrite CWM recovery, so you'll have to go back to fastboot and reflash.

If you did it right, CWM recovery should start. In CWM recovery, you use Volume Up and Volume Down to move the highlight up and down, and the Power button to select options.

If you need to root:

Select 'install zip from sdcard'

Then select 'choose zip from sdcard' or 'choose zip from external sdcard' depending on where you placed the Superuser zip file.

Now navigate to your Superuser-3.1.3-signed-arm.zip and select it

Choose 'Yes Install Superuser-3.1.3-signed-arm.zip'

Go back to the main menu and choose 'reboot system now' to restart android. You should now be rooted.

To test it out, when the A2109 finished booting, try this at the command prompt:

Code:

adb shell
su

If you've rooted successfully, the prompt should change from a $ to a # (meaning you have root access).
Type 'exit' twice at the command prompt to leave the adb shell.

If you are running the stock firmware, each time you boot into Android it will overwrite ClockworkMod recovery with the stock recovery. You can prevent this by renaming the recovery-from-boot.p file in your /system folder to something else. You can do this in ES File Explorer:

In ES File Explorer under Setting, choose 'Root Settings' and make sure that 'Root Explorer', 'Up to Root', and 'Mount File System' are all checked.

Navigate to the /system folder

Long press recovery-from-boot.p and choose Rename

Rename it to something else, like recovery-from-boot.p.bak

Go back to Settings -> Root Settings and uncheck 'Mount File System' to put the system partition back to read-only.

After renaming the recovery-from-boot.p file, you'll have to go back into fastboot and reflash ClockworkMod recovery one more time, but now it will "stick".

Let me know here if you have any questions or need anything clarified.

I pay'd to someone to flash this mod on my Lenovo IdeaTab A2109...i really want to know doing this by myself.

I would like to ask you few questions regarding youe ROM ... hope that your answers will help me complete this task:

1) If i already have a custom rom installed on my IdeaTab - do i have to do the bootloader unlocking ?

2) If i have the ICS rom - which from the two img's i need to use? 6.0.1.9c.img OR 6.0.1.9d.img ???

3) The Superuser-3.1.3-arm-signed.zip combine the ROM & ROOT? if do, i just need to flash it and it install the ROM and make the ROOT too at the same time?
If not...where is the ROM ?

I would appreciate your help so much!
I realy want to learn how to do it...
All best!

Seeing that you're running the MCL ROM, I know that you've got the bootloader unlocked, a new recovery image (e.g. clockworkmod) flashed, and root access through Superuser (I believe this is necessary). According to your info, you have the ROM already installed. Do yourself a favor -- push power and volume up at the same time, when your tablet is off, for five seconds or so. You'll see which version of clockworkmod (cwm) you are running. Hopefully it is 6.0.1.9c. You can easily reboot from that menu.

I encountered a speedbump when trying to follow the original instructions from the Lenovo forum. I don't have ES File Explorer so I tried to make CWM stick using adb. Apparently, the Linux Android SDK version of adb is unwilling to run as root, saying:

To enable adb remount you need to make this an insecure boot.img, by splitting the boot.img replacing the adbd with one from ICS boot.img, then edit the default.prop repackage boot.img and flash.

or you can

adb shell

mount -o remount,rw /system

This is same thing as adb remount, but doesn't require any modifications to boot.img

I use choice one as I always modify boot.img for reason or other.

I recall trying option 2 but it didn't work so I didn't mention it. The command appeared to work and the filesystem showed up as rw but it still could not be written to. I don't recall the exact error message any more.

And then, I can't seem to tap Volume Up fast enough. It just boots into android again. (it says "cold booting linux" right before). Is there some other way to boot into CWM? I think my reflexes are just old...

EDIT: I got it! Thanks.

I followed the steps to unlock the bootloader, and that worked (I think -- how would I check it?)

OK. I feel a bit foolish. I'm using a mac, but the Linux instructions should work, right? Everything is fine until I get to this step:

Actually, dont tap it, hold it instead until you see the little line of text on the top left of the screen and then immediately release it
